Global warming effect on Lake Tanganyika

Considered one of the African Great Lakes, Tanganyika is the globe's second largest lake and second deepest, after Russia's Lake Baikal. It consists of 17 percent of the world's surface freshwater. Virtually as much water as all five of the North American Great Lakes integrated.

At even more than 10 million years old, Tanganyika is amongst a group of only 20 ancient lakes in the globe. As in numerous lakes all over the world, water temperature level is on the rise in Lake Tanganyika.

This and various other climate-related factors are causing considerable but subtle changes that threaten the environmental security of the lake and the livelihoods of people who depend on it. Unlike retreating glacial mass, there is in fact something that can be done to reduce the effects of climate change in lake areas. By recognizing environment change as a major aspect, not just for how it influences the wellness of the lake however the well-being of people living around it, conservationists and researchers dealing with Lake Tanganyika are already leading a trail forward.

In the many part, the lake has fairly high quality water, except in a few locations where urban and industrial overflow has actually impacted the lake. Given the importance of Lake Tanganyika, why we have not heard more about the effects on lakes such as this in the climate modification discussion. Not only is this affecting the ecological security of the lake, it has actually resulted in a 20 percent reduction in biological efficiency in the lake.

Researchers are worried about how continued warming will influence fish stocks and the lake's rich biodiversity. Decreased fish catches would influence millions of people living in the lake area, lots of whom live on less than a dollar a day and depend on the lake for basic human demands - the protein from fish and clean water to consume.

The lake is amazing in various other ways, not the least of which is its extreme depth. At nearly a mile deep (1.472 km), it is among an unique group of lakes. The warmer surface waters never blend totally with the cooler water at depth.

Lake Tanganyika takes place to have among the lengthiest temperature records of any lake on the planet. A century ago, scientists started gauging temperature profiles to a depth of 1,000 meters. From these records, scientists are discovering that Lake Tanganyika's surface waters are warming more rapidly than its depths.
This has the effect of producing an even sharper gradient in between the upper and lower layers of the lake.

Finding the optimal nutrient concentrations in a lake is a fragile balancing act. With insufficient, the lake could not support aquatic life. With too much, the lake becomes excessively effective and can develop hazardous algae blooms and excessive weed development. Another one-of-a-kind feature about Lake Tanganyika is that its surface waters are low in nutrients yet support an unbelievably efficient fishery.

This is possible due to the fact that of an occasional upwelling of vitamins and mineral rich water from the bottom of the lake. Analysts are already seeing indicators that the amount of blending has actually lowered. Although the science is rapidly developing, they think it will be several years before analysts have the capacity, assuming that required information are available, of predicting how close the lake is to reaching an important "tipping point.".

For people living near inland lakes, this seems like the equivalent of the apocalyptic scenarios for water level increase and even more intense storms we've all become aware of and started to see in coastal areas. And yet many sources of funding for research and preservation programs on Lake Tanganyika have fallen off in recent times.

I have come to the conclusion that we all have a little blame global warming and its consequences and guilt even more politicians who do not slow down.
